Abstract
A structure capable of reducing the amount of transferred digital image data of a digital display has a digital image and timing control unit for controlling the receiving and transfer of image data and providing timing control. The digital image and timing control unit includes at least one first and second registers, a data address flag unit, and a control logic. The first and second registers serves to buffer the image data of the n-th image data line and (n+1)-th image data line. The control logic compares the image data and enables the flags in the data address flag unit corresponding to the image position to be updated, so as to determine the image data to be transferred.
Claims9
A structure capable of reducing the amount of transferred digital image data of a digital display comprising:
- a display area for displaying digital image;
- a digital image and timing control unit for controlling receiving or transferring of digital image data and providing timing;
- a horizontal signal processing unit for retaining one line of input digital image data under the control of the digital image and timing control unit, and transferring the retaining image data to the display area;
- and
- a vertical signal processing unit for outputting scanning signals to the display area under the control of the digital image and timing control unit to drive the display area for displaying input digital image;
- wherein the digital image and timing control unit includes at least first and second registers, a data address flag unit having a plurality of flags, and a control logic;
- the first and second registers buffer the image data of n-th image data line and (n+1)-th image data line for comparing image data using the control logic to enable flags of the data address flag unit corresponding to image positions required to be updated, thereby determining image data to be transferred.
